Page 10: Gain Factor
Gain factor 17. GAIN FACTOR The analogue inputs A1 and A2 have a standard range of 0 ~ +5Vdc. To use them externally, remove the jumper caps on SK2 and SK3. The internal 5V voltage source can only be used for testing purposes. When the input voltage is too low you can amplify it x4 / x15. -

Input is generally "high" (1), connection to GND makes the input "low" (0) Analogue inputs (e.g. temperature sensor, potentiometer, ...) 0 ... +5VDC MAX! If the jumper is mounted, then you can use the internal voltage and adjust it using RV2/RV1. If the jumper is not mounted you must use the external voltage A2/A1.

Page 14: Digital Outputs
Connection / settings Select the correct address in the test program DIGITAL OUTPUTS : 8 open collector contacts, to be connected with suitable inputs. These exits function as ‘dry contact points’: you need an external voltage to control a component such as a LED or a relay switch. - Page 15 • Start “Setup.exe”, this software is located at the folder K8055 from the Velleman Software CD.

Page 16: Test Procedure
LED LD3 'Power' lights up if the connection has been executed properly. After startup LD8 (output 8) will flash momentarily to indicate that the circuit works as it should. Start the program 'K8055_Demo.exe'. Next press the 'connect' button to connect the K8055 with the computer. - Page 17 Test procedure The message "Card x connected" is displayed if the connection is successful, see fig 3.0. FIG 3.0 You can now simulate the inputs via push buttons Inp1 through Inp5. The matching check box remains ticked off as long as you keep one of the push buttons pressed down. Always tick off the check box for the matching output if you wish to test a digital output.
- Page 18 Test procedure Counter 1 & 2 are hardware integrated 16-bit counters, they are triggered by INP1 & INP2. You can test the counter with push buttons Inp1 and Inp2 : the counter adds 1every time one of these two buttons is pressed.
